1351In addition to the colours defined above, @@RXVT_NAME@@ offers an
1352additional 72 colours. The first 64 of those (with indices 16 to 79)
1353consist of a 4*4*4 RGB colour cube (i.e. I<index = r * 16 + g * 4 + b +
135416>), followed by 8 additional shades of gray (with indices 80 to 87).
1355
1356Together, all those colours implement the 88 colour xterm colours. Only
1357the first 16 can be changed using resources currently, the rest can only
1358be changed via command sequences ("escape codes").

1375
1376If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1377their act together, rxvt-unicode will support C<rgba:rrrr/gggg/bbbb/aaaa>
1378(recommended, but B<MUST> have 4 digits/component) colour specifications,
1379in addition to the ones provided by X, where the additional A component
1380specifies opacity (alpha) values. The minimum value of C<0> is completely
1381transparent). You can also prefix any color with C<[a]>, where C<a> is on
1382to four hex digits specifiying the opacity value.
1383
1384You probably need to specify B<"-depth 32">, too, and have the luck that
1385your X-server uses ARGB pixel layout, as X is far from just supporting
1386ARGB visuals out of the box, and rxvt-unicode just fudges around.

1389background, and an almost opaque pink foreground:
